FEEDING DEVICE FOR COB-N-SHREDDERS.

Specification of Letters Yatent.

Application filed April 1i), 1914. Serial No. 331,012.

T all whom it may concern Be it known that I, Pn'rnn Wan/mun, a citizen of the United States, residing at Melj rose, in the county of Stcarns and State of Minnesota, have invented new and useful 'Improvements in Feedin Devices for Corn- Shredders, of which the ollowing is a specification.

This invention relates to automatic feed- .m'in devices for corn shredding machines, re erence being had to that class of machines ivhich are used for shredding and disintegrating corn stalks for feeding purposes.

The invention has for its ob eot to produce a simple and efficient device whereby the i'b ands of bundles of stalks will be ant and the stalksbe 3 read out so as to be presented {the shred er-ina relatively thin'layer,

whereby the shredding operation will be 2Q facilitated'and-better results will be obtained "whenthejstalks are fed by hand.

, further objee't" oithe' invention is to roduce 'q mpa and elficient feeding device,

. 'rvhereby "theqcorn stalks as they are being fed to the shredde'r will be so manipulated with respect t the shredding mechanism so as toi facilit'ateand improve the operation of said shredding mechanism.

,VVith theseand otherends in view which .50 will readily appear as the nature of the in- :ention isbetter understood, the same con- ."rii'stsin the improved construction and novel arrangement and combination of parts which wfill be hereinafter fully described and par- .tililticul arly pointed out in the claims.

n the accompanying drawings has been illustrated asimple and preferred form of the invention, it being however, understood that no limitation is necessarily made to the =49 'recise structural details therein exhibited,

, ut that changes, alterations and modifications Within the scope of the claims may be resorted to when desired.

In the drawings,Figure 1 is a. top plan 46 view of a feeding device constructed in accordance with the invention. Fig. 2 is a side elevation of the same. Fig. is a longitudinal sectional view taken on the line 3--3 of Fig. 1. Fig. 4 is a transverse sectional view 5.0. taken on the line 44 in Fig. 1. Fig. 5 is a transverse sectional view taken 'b'nthe line 5-5 in Fig 1.

Correspondin parts in the several figures -j are denoted by like characters of reference. i6v The bed or table. 15 of the improved feeder is providedwith side flanges l6 and with an inclined top member 17 combining to forma houslng ad acent to theJrecelvlng end of the shredding machine, said receiving the ends of the bed or table, the latter being Patented June 1, 1915.

provided with guide members of L-shaped cross section, including cleats and flan cs 22' extending therefrom, between and eneath which the conveyer is guided and be tween the lateral flanges 22 of which bundles of corn may be introduced and placed on the conveyor. The latter may be of any well known chain and slat construction or of any construction that will enable it to carry the bundles of corn along.

' The L-shaped guide members are interrupted at a suitable \distance from the flanges 16 of the housing, and adjacent-t0 said flanges 0r uprights 23 is supported a crossbar 23; another cross bar 24 is secured on the flanges 16. These cross barsafi'ord bearings for shafts 25 having cranks 26 and provided at theirhrearv'vard ends with-bevel gears 27 meshing with bevel pinions 28 on a shaft 29 which is supported for rotation on the side flanges 16 near the forward ends of the latter. Supported on each crank 26 is an arm 30 carrying at its inner end a broad hoe-shaped cutting blade 31. The outer ends of the arms 30 are connected'by links 32 with bearings 33 on the sides of the bed or table 15. It follows from this construction that when the shafts 29 are rotated, the cutter at each side will be carried through an orbital course, the blade being moved transversely with respect to the'conveyer while the cutting edge of the blade is disposed longitudinally with respect to the conveyer, thus causing said cutting edge to engage and cut the bands whereby the bundles are tied, while the blade serves also to spread or distribute the corn stalks over the entire width of the bed or'tuble' of the machine.

Supported for rotation in the-side flanges 16 near the rearward end of the device is a shaft 34 carrying a. reel 35, said shaft carrying also apinion 36 meshing with a driving gear 37'wh'ich in turn meshes with a pinion 38 on the shaft 20 over which the rearward end of the endless conveyor is trained and from which the reel derives its motion.

The shaft 29 has been shown as being provided with a sprocket Wheel 39 for the purpose of receiving motion from some moving part of the shredder in connection with which the feeder is used. A chain may be utilizedfor transmitting motion from the shaft 29 to the-shaft 34- carrying the driving pinion 36, thereby transmitting motion to the endless conveyer and to the reel.

In the operation of this device the bundles of corn are placed on the conveyer between the guides 29, and the bundles are carried by the conveyor beneath the cutting and spreading members, whereby the. bands are cut. and the stalks are distributed evenly over the conveyer to be carried by the latter until engaged by the reel. whereby the stalks are flattened out and fed to the shredder in the. best condition to be efficiently operated upon. I

It will he observed that the guides composed of the elements 22 and 22 Whereb the endless conveyor 19 is guided are interrupted adjacent to the uprights 23' that support the cross bar 23 which, together with the cross bar 24, carries the crank shafts 25 whereby the cutting and spreading members are actuated, thus permitting said cutting and spreading members to swing more closely to the face of. the upper lead of the conveyor than would be possible if the guide flanges were not interrupted. The corn stalks may thus be spread more thinly and exenly from the face of the conveyor. and the operation of the device is thereby materially improved.

Having thus described the invention, what is claimed as new, is:'

1. In a feeder for sin dding machines. a frame. an endless conveyor. guides fo said conveyor. crank shafts supp rted longitudinally above the conveyor, combined cutting and spreading members pivoted on the cranks of said shaft and having blades movable transversely of the conveyer and the cutting edges of which are disposed longitudinally with respect to the conveyer, and links connecting the outer ends of said cutting and spreading members with the frame; the guides of the conveyor being interrupted in the path of the cutting and spreading members, in combination with means for actuating the conveyer and the crank shafts.

2. In a machine of the class described. the combination with a conveyer and a frame whereon said conveyer is guided, of crank shafts supported longitudinally above the same. cutting and spreading members including arms pivoted on the cranks of said shafts, and broad hoe-shaped cutting blades fixed on the inner ends of said arms, movable transversely of the conveyer and having cutting edges disposed lon itudinally with respect to the conveyor, links connecting the outer ends of said arms with the frame. and means for actuating the conveycr and for rotating the crank shafts in opposite directions imparting to the cutting and spreading members orbital movements whereby they will be caused to sweep over the top face of the conveyer transversely toward the outer edges of the latter. I

In testimony whereof I afiix my signature in presence of two witnesses.
